VirtualDspinNetwork

1) Functional Description

The Virtual Dspin Network aims to connect a two-dimensionnal array of TSAR clusters together.

It virtualizes two virtual channels (usually the primary channel and the memory-coherence channel) on two physical networks VirtualDspinArray of different size (usually one for command paquets and one for response paquets).

The two physical networks are not connected between them.

It implements the optimized and confined sequential broadcast protocol on first network for second channel and the Hypertransport routing on both networks for the first channel.
